I've jumped a Sabre, Diablo and Stileto 170 is the last year and 1/2, at 1.4 wingload I fould the Diablo opened the smoother (ie pretty long snivel); had the fastest sink rate in full flight; had quite a slow sink rate with toggles stowed or in rear risers (slower then the Sabre); had the highest toggle pressure and front riser pressure of the 3; had no overstreer that needed correction; had the least amount of surf of the 3 in straight in approaches (sorry, I dont hook, so cant compare high speed approaches); had very fast turns! Fun canopy at 1.4, but not the most forgiving. Remi
